Abstract. Binary
transition metal oxide solid solutions comprise a useful set of materials whose
properties can be tailored by compositional variation. A particularly
interesting group of them places one of the metal cations in a chemical
environment that is atypical for the thermodynamically stable cation in its
native solid state oxide. Depending upon the solid solution and the task at
hand, compositional variation may allow for tailoring the physical and chemical
properties of the solid solution to the desired application. This review presents
a characterization of several binary metal monoxide solid solutions over a
range of concentrations, with an emphasis on their surface analysis. Surface
compositional, structural, magnetic and electronic characteristics all may be
varied by choice of bulk solid solution composition, and these effects are
particularly dramatic for several nanoscaled systems described in the review.
